Answer 1

Answer:

AC AND BCD IS NOT STRAIGHT Line

Answer 2

Answer:

x = 115°

Step-by-step explanation:

In the given figure, ABCD is a parallelogram.

AO = CO = DO , it means O is center of circle with passing point A, C and D.

If angle subtended on same arc then arc angle is half of central angle.

Therefore, $\angle ADC = \dfrac{1}{2}\angle AOC$

$\angle ADC = \dfrac{1}{2}\times 230^\circ$

$\angle ADC =115^\circ$

In || ABCD

$\angle B=\angle D$        ( opposite angles of a parallelogram is equal)

$\angle B=115^\circ$            $\because \angle D = \angle ADC=115^\circ$

Hence, The value of x is 115°
